Follow up on 1094 - Windows Directory Resolver error for ALPMDB dir:. scan

**Please provide a set of steps on how to reproduce the issue**:
See #1094: cataloging ALPM symlinks ends in an error condition on windows

`syft/pkg/cataloger/alpm/parse_alpm_db.go:110` <-- Windows is unable to resolve the directory correctly and this will end in an error condition. Previously it would result in a panic

**What you expected to happen**:
syft should scan ALPM DB

**Anything else we need to know?**:
Windows Path Based - Darwin/Linux works as expected

Start with syft/pkg/cataloger/alpm/parse_alpm_db.go:110 and issue #1094. Reproduce an ALPM database scan on Windows, then compare the path behavior with Darwin/Linux; done means syft scans the ALPM DB without a directory-resolution error or panic.
